Assuming that Hund's rule is violated the bond order and magnetic nature of the diatomic molecle `B_(2)` is

A

1 and diamagnetic

B

0 and diamagnetic

C

1 and paramagnetic

D

0 and paramagnetic

Text Solution

Verified by Experts

The correct Answer is:
A
`B_2` (total number of electrons =10)
`sigma1s^2 sigma^**1s^2 sigma^** 2s^2 pi 2p_x^2 = pi 2p_y^0 sigma 2p_z^0`
So, bond order ` = (6 - 4)/2 = 1` and molecule will be dimagnetic.
